US 2018/0132200 A1 · TECHNIQUES AND APPARATUSES FOR SYNCHRONIZATION, SCHEDULING, BANDWIDTH ALLOCATION, AND REFERENCE SIGNAL TRANSMISSION IN A 5TH GENERATION NETWORK

Abstract

As wireless communication technology advances, the bandwidth usage of wireless communications systems becomes increasingly flexible. For example, different user equipment (UEs) may support different bandwidths or radio frequency capabilities. However, a scheduling entity may not know wireless capabilities or characteristics (e.g., supported bandwidths, RF chain configurations, reconfiguration times, and/or the like) of the UEs for which the scheduling entity is to manage communications, which may hamper the ability of the scheduling entity to take advantage of the advances in flexible bandwidth usage described above. Techniques for synchronization, scheduling, bandwidth allocation, and reference signal transmission in a wireless communications system associated with flexible bandwidth allocation, such as a 5G network, are described herein.

Dependent claims

A method of wireless communication, comprising:

identifying, by a network device, a channel that supports communications with a plurality of user equipment (UEs),
wherein at least two UEs, of the plurality of UEs, support different bandwidths on the channel;
and
transmitting, by the network device, at least two synchronization signals, wherein at least one synchronization signal, of the at least two synchronization signals, is transmitted in one or more sub-channels of the channel that are not located at a frequency center of the channel to permit the at least two UEs to receive the at least one synchronization signal.

1 more element

A wireless communication device comprising:

a memory;
and
at least one processor operatively coupled to the memory, the at least one processor configured to:
transmit radio frequency (RF) chain information identifying an RF chain capability of the wireless communication device and at least one parameter related to the RF chain capability;
receive scheduling information identifying a particular sub-channel of a channel,
wherein the channel supports communications with a plurality of wireless communication devices based at least in part on respective RF chain capabilities of the plurality of wireless communication devices;
and
communicate on the particular sub-channel based at least in part on the scheduling information.
